On Saturday at UFC 14, Chael Sonnen attempted a spinning backfist that was ducked by Anderson Silva. Sonnen tripped, took a knee to the grill, and the fat lady started singing. Two days later on WWE Raw, CM Punk paid a bit of tribute to one of the more theatrical MMA endings in recent memory: he missed his own spinning backfist, and took a knee from Daniel Bryan. Well played, fellow sports entertainment company.
